A lot of America especially has an issue with too many lights, and the lights themselves are too bright relative to the population. Found what I thought was a cool image on Wikipedia Commons while searching the subject that has the light use relative to the population density. Green's lots of light use, red is lots of population density. America's bright green light use. Yellow is fairly equivalent light use to population density. [1]
